Hip and knee angle measurements in degrees through a 20-point movement cycle for 39 children. The data represents the angular positions of hip and knee joints during normal walking gait, captured at evenly spaced time points throughout the gait cycle.
Format
A data frame with 39 rows and 3 variables:
- subject_id
subject identifier
- knee_angle
a
tfdcolumn of knee-joint angles (degrees)- hip_angle
a
tfdcolumn of hip-joint angles (degrees)
Details
Data is also included in the fda package in another format.
